I'm sure I could beat all three of the current candidates. Hillary, she's slow and old so I could take her with one punch. I would avoid her face though. She's ugly enough as it is.

Hussein Barrack Obama may be pretty quick and agile but I think I could take him. He’s liberal and they tend to suck as fighters. He’d probably call up the country of France and then again, no worries. http://www.albinoblacksheep.com/text/france.html
The only war they won was when they fought against each other and then it was a toss up of who sucked worse.

McCain would probably be the toughest. He’s been through much torturing so pain may not be an issue but he is old. Ya can’t fight with a fractured patella.
